BICYCLE-LOCK.

SPEGIFICATION forming part 0f Letters Patent N o. 707,310, dated August19, 1902.

Application filed April 5 1902. Serial No. 101,577. (No model.)

To fully describe my invention, reference is;

made to the accompanying sheet of drawings, forming a part of thisspecificatiom--infwhich similar reference numerals indicatecorresponding parts in each ofthe figures.

Figure 1 represents an elevation of a safetybicycle fitted with myimprovements. Fig. 2 is a sectional elevation, on a larger scale, of

the steering-head and the locking attachment.

Fig. 3 is a similar vieW with the head turned around at right angles andlocked in that position. Figs. 4 and 5 are plan viewsof Figs. 2 and 3without the cap, hereinafterreferred to; Figs. 6 and 7, detail viewshereinafter referred to. f

The disk 2 is rigidly secured to the top of the socket 3, in which thesteering-post 4 works. This disk is sufficiently large to allow the end6 of a lock-bolt 7 to pass through. Above the disk 2 the disk l0 issecured t0 the steering-post 4 in such a Way that it iscomf pelled toturn with a post, but can be readily removed, if required. This may beeected by the radial screws 13 in the disk engaging the slits 14 in thetop of the steering-post. Two holes 15 are made through the disk 10diametrically opposite each other in a line parallel to the axis of thesteering head. These holes are the same distance from the center of thepost as the bolt 7, and the bolt is a springebolt actuated by the spring18. Therefore when the steering-wheel 2O is turned The short studs 40maybe placed heady downwardvin the holes 15, so that when the bolt 6passes into either hole it lifts the stud therein and presses its topagainst the under side of the boss 41 of the cap 42, screwed on the topof the steering-post 4. A number of holes 44 are made in the boss 41, sothat if any attempt is made to unscrew it to tamper with the parts theupwardly-pressed lstud "is forced into one of the holes in theboss ofthe cap and the latter is locked. Fig. 6 is a separate View ofAone ofthe studs, and Fig. 7 is a diametrical section of the disk l0 with astudin one of the holes.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I- claim isl In a bicycle, the combination with the head or socketand the steering-post therein, of a transversely-arrangeddisk at theupper end of said socket, a second disky carried by the post adjacent tosaid iirst-named disk, and a locking-bolt slidingly supported, said boltpassing through an opening in the first disk and engaging a recess inthe second disk, substantially as described.

In witness whereof I have hereunto set my hand in presence of twoWitnesses.
